Will this work, it looks like it's an OEM MCE remote, and it sounds like it's bigger brother the GP-IR02BK will work with the MCEUSB config.
I must confess that I am still waiting for my Torrent to download, so I don't have LinuxMCE. I have been following the project for about a year now, and v1.1 (Kubuntu Development?) worked, but took three days to install, and it was sluggish. 704RC1 DVD failed at start up and I am now trying 710RC1. However, I am unsure of what difference there are between 704 and 710, besides the Ubuntu core.
